Table 5 H. Depths reduced from dynamic meters to meters, the acceleration of gravity at 



sea-level being g.8o. 



Table 6 H Corrections to table 5 H for values of the acceleration of gravity different frotn Q.80. 



Example Depth 2676 dynamic meters : Meters. 



Table 5 H gives for the depth of 2600 dynamic meters 2652 



Proportionality table gives for the depth 76 dynamic meters +78 



Table 6 h gives for gravity 9.782S at sea-level and depth 2676 dynamic meters -j- 4 



Geometric depth corresponding to the dynamic depth 2676 2734
